Projector for images formed by compound photography

ABSTRACT

A device for projecting upon a screen the images formed and recorded by the compound photographic camera which comprises a first lens directed toward a subject, an aperture movable in a plane within said first lens or in the vicinity thereof and at a right angle relative to the optical axis thereof and a microlens group disposed behind a plane upon which an image in the air is formed through said first lens, whereby said image is further split into finely divided images and recorded upon a sensitized material disposed behind said microlens group and a plurality of images of other subjects are recorded upon said sensitized material in the same manner as described above.

1. A projector having an outer wall surface and adapted for projecting images formed by compound photography comprising a first projection lens, said lens having an optical axis; a first plate having an aperture therein movable in a plane perpendicular to said optical axis; a developed original comprising a second lens consisting of a plurality of microlenses having a plurality of images formed thereon, said original spaced from said first lens along said optical axis; a holder adapted to have said original detachably mounted thereon, said holder having an inner side facing said first lens and an outer side remote from said first lens; a second plate having an aperture movable in a plane perpendicular to said optical axis; said movable plates being located adjacent to said first lens; an illumination means located on said remote side of said original holder for illuminating said original; a projection screen upon which is projected an enlarged image of said original; an imagE selection assembly located upon said outer wall surface of said projector for adjusting the positions of said movable plate apertures with respect to each other so as to select an image to be projected; a microlens plate disposed adjacent said original on the remote side of said holder for illumination of said original; a pair of drive shafts; means for supporting said microlens plate and having connections to said drive shafts for movement by a small distance in both horizontal and vertical directions; said movement of said microlens plate being in response to rotation of said drive shafts; a movable mirror spaced from said microlens plate; means for supporting said movable mirror for rotation about both of the horizontal and vertical axes; means for rotating said movable mirror about both of the horizontal and vertical axes in response to the rotation of said drive shafts; and a light source disposed on one side of said movable mirror, whereby said movable mirror is so rotated and said microlens plate is so moved that the position of the image selected by said image selection assembly and an image of said light source may be symmetrically located with respect to the center of said original.
 2. A projector as set forth in claim 1 comprises said pair of aperture selection movable plates which are slidable in directions perpendicular relative to each other and each of which has an elongated slot formed therethrough at a right angle relative to the direction of slidable movement thereof; a pair of reversible motors having electrical circuits for selectively driving each said drive shaft in both forward and reverse directions; change-over switches interconnected in the circuits of said motors for reversing the directions of rotations of said motors; means for actuating said switches so as to rotate said motors in such direction that said pair of movable plates may be moved to an aperture position selected by said image selection assembly; means for holding said switches in closed positions; and means operatively coupled to said drive shafts for opening said switches when each of said apertures is located at said selected position.
 3. A projector as set forth in claim 1 comprises said pair of aperture selection movable plates which are slidable in directions perpendicular relative to each other and each of which has an elongated slot formed therethrough at a right angle relative to the direction of the slidable movement thereof; a pair of reversible motors having electrical circuits for selectively driving said drive shafts in both forward and reverse directions; change-over switches interconnected in the circuits of said pair of motors for reversing the directions of rotation of said motors; means for actuating said switches so as to rotate said motors in such a direction that said pair of movable plates may be moved to an aperture position selected by said image selection assembly; means for holding said switches in closed positions; means operatively coupled to said drive shafts for opening said switches when each of said apertures is located at said selected position; a cam carried by a further shaft coupled to each of said drive shafts; and an engaging member movably mounted on said switch operation holding means and adapted to be moved by said cam when said switch is opened, said engaging member being adapted to be adjustably positioned relative to said cam, thereby adjusting the timing of opening said switch.
